The ICD-10-CM code N60.49 might also be used to specify conditions or terms like galactophoritis, mammary duct ectasia, periductal mastitis or plasma cell mastitis.

Unspecified diagnosis codes like N60.49 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.
